- State the job, users, source material, and acceptance checks before naming candidates.
- Run every candidate on the same permissioned inputs and record the exact product surface used.
- Score accepted outputs, critical failures, reviewer time, and workflow fit separately.
- Check current administration, retention, export, regional, and integration terms at the official source.
- Pilot with human approval and a rollback path before replacing the current workflow.
